Here's a strange one: I recently acquired
two Shugart 851 drives from
another cctech-er. They were in nice shape and operate fine. The weird
part is their form-factor.
I have 8 or 10 other 8" drives in my collection, both half-height and
full-height, including two other 851 Shugarts. All of these are 8.5" wide,
with faceplate and frame being exactly the same size.
These two "new" Shugart units are _9.5"_ wide at the faceplate and require
a clearance of about 9-1/8" for the frame. Can anyone explain this odd
sizing? Were they perhaps manufactured against an earlier standard?
IIRC, the "R" suffix drives are intended to be rack-mounted in pairs. I have
no idea, though, how that could be better than using the standard-width
drives since either way they're going to need some mounting hardware.
Nothing on these units indicates an "R" model, but your explanation makes
sense. I'd expect there to be an obvious way to fasten the drives
together along their common edge, but don't see anything that jumps out at
me.
Live and learn. If anyone has a particular need for this type of drive,
let me know? A swap for one of the 8.5" wide units would be ideal.
